heterogeneous catalyst

Why are the most common heterogeneous catalysts finely divided or porous solids?

Well it makes sense to me that since a solid heterogeneous catalyst cannot be blended with the reactant perfectly, then we probably want to at least maximize the surface area.

Re: heterogeneous catalyst

Most heterogeneous catalysts are solids, and in order to maximize catalyst-substrate interaction it needs to be porous or finely divided.

Re: heterogeneous catalyst

Because it wants to maximize the surface area of the catalyst, so it is able to be involved in more places.
